I thought the size limits for YTMNDs were 1.5 mb. The image is too small, though. To keep filesize down you can try lowering the framerate, diluting the colours. I think for larger dimensions it'd be a fair tradeoff.

Wow this is ridiculously bad. I don't know how anyone is going to give this more than a 1. You think this constitutes a YTMND? Take your sh*tty 100px composition of 3 videoclips to YouTube and see what they think- don't bring it here. You sicken me.
